Process of refining hydrocarbons



Patented June 24, 1947 7 2,422,875 PROCESS OF REFINING HYDROCARBON S Per Henning Wilhelm Agren, Nynashamn, Sweden, assignor to A. Johnson & 00., New York, N. Y., a company of Delaware No Drawing. Application June 24, 1944, Serial 542,004. In Sweden August 17, 1942 9 Claims. 1

The present invention relates to a new method of refining liquid and gaseous hydrocarbons, such as cracked or uncracked gasoline, kerosene and similar products from petroleum, shale oil, hydrocarbon gases containing organic sulfur compounds, etc. The invention is characterized by the fact that the hydrocarbons in the vapor and/or liquid phase with or without the addition of hydrogen or hydrogen containing gases is brought in contact with a catalyst entir or at least partly consisting of aluminous cement, with a content of A120: amounting to at least 25 per cent.' According to the invention the cement may e. g. be employed in mixture with compounds of iron or manganese, suitably in the form of oxides or hydroxides, e. g. admixed in the form of bog-ore. It is also possible to em oy metallic iron or manganese which is mixed into or produced by reduction of the catalytic compound.

The invention is particularly useful for desulfurizing sulfur containing hydrocarbon mixtures which, upon treatment withthe aforementioned catalysts, will give oil? the sulfur in the form of hydrogen sulfide with a high yield of high quality refined products. The desulfurizing is of partic: ular importance in the production of knock-stable motor fuels, the sensitivity of which to antiknock compounds, such as tetraethyl lead, iron 2. A process according to claim 1 in which the hydrocarbons are contacted at least partly in the vapor phase with the catalyst.

3. A process according to claim 1 in which the hydrocarbons are contacted at least partly in the liquid phase with the catalyst.

4. A process according to claim 1 in which the hydrocarbons are contacted with a catalyst comprising aluminous cement in mixture with a. catalytic agent selected from a class consisting of iron and manganese oxides and hydroxides.

5. A process according to claim 1 in which the hydrocarbons are contacted with the catalyst in mixture with a gas at least partly consisting of hydrogen.

6. A method of refining gasolines for removal of sulfur which comprises contacting a gasoline with a catalyst consisting of aluminous cement in admixture with a catalytic material selected from a class consisting of iron and manganese carbonyl etc., is considerably increased by a lowering of the sulfur content.

If hydrogen is present during the catalytic treatment, a hydrogenation of di-oleflnes possibly present will take place, which is advantageous since it will improve the stability of the a The catalyst is active at both atmospheric and high pressures up to atmospheres and more. at temperatures ranging from about room temperature (20 C.) up to 500 (Land more.

I claim:

1. A process for the refining of hydrocarbons, comprising contacting said hydrocarbons with a catalyst at least partly consisting or aluminous cement, having a content of Per cent.

A: of at least 25 oxides and hydroxides, said aluminous cement having a content of A1 03 of at least 25 per cent.

'7. The process of claim 6 wherein said catalytic material is bog-ore.

8. A process according to claim 1 in which the hydrocarbons are contacted with a catalyst comprising aluminous cement in admixture with a catalytic agent selected from a class consisting of metallic iron and manganese and mixtures thereof.

9. The process of claim 6 wherein said catalytic material is selected from a class consisting of metallic iron and manganese and mixtures thereof.
